Boca Hydro Potassium Nitrate – 13.5-0-46.2
Premium Water-Soluble Potassium & Nitrate Nitrogen Fertilizer
Boca Hydro Potassium Nitrate is a premium-grade, fully water-soluble fertilizer delivering Nitrate Nitrogen (NO3−) and Soluble Potassium (K2O) in one clean, fast-dissolving formula.
It is ideal for crops requiring fast-acting, immediately available nitrogen and potassium, making it perfect for fruiting vegetables, ornamentals, leafy greens, and flowering plants during mid-to-late growth stages.
Nitrate nitrogen promotes lush green growth without ammonium buildup, while potassium boosts flowering, fruit quality, plant resilience, and overall performance.
Chloride-free and highly soluble. Excellent for hydroponics, fertigation, drip irrigation, foliar feeding, pots, containers, greenhouse crops, and garden plants.
